Abstract
The utility model provides a kind of cleaning validation detachable sampling cotton swab, and comprise sampling head, thief rod, described thief rod is connected by helical structure with sampling head, and the cross section of described sampling head is oval.The described cleaning validation detachable sampling cotton swab chemical cotton swab that can be used in pharmaceutical industry cleaning validation process samples and the sampling of microorganism cotton swab, after sampling completes, sampling cotton swab is in the detachment process of glass test tube, only need to grasp thief rod to be rotated counterclockwise, being separated of sampling head and thief rod can be realized.Thief rod after separation is recyclable and reuse, and avoids the wasting of resources.
Description
Technical field
The utility model relates to a kind of sampler, especially relates to the detachable sampling cotton swab of a kind of cleaning validation.
Background technology
Current medicament compartment carries out the chemical sampling of cleaning validation and microorganism sampling all needs to use wiping cotton swab, divide from shape and mainly contain two kinds, be integral type cotton swab, wherein a kind of thief rod is smooth, another kind of having easy Origuchi near sampling head position, but from actual application, all there are some problems in former cotton swab.
The first sampling cotton swab, after sampling completes, needs before putting into glass test tube to use scissors to cut off thief rod, causes interference with the position preventing hand handled to microorganism result or chemical results.The process using scissors to cut off thief rod, is just present in because scissors cleaning does not thoroughly cause the risk of microbial contamination, causes result false positive, thus causes cleaning validation result originally defective.
Although the second sampling cotton swab has easy Origuchi in design, but practical operation is more difficult, due to the restriction of material, if cotton swab bar is excessively crisp, easily surprisingly fracture in sampling process, if material fragility is bad, cause so again not frangibility, therefore to the processing of cotton swab with to produce be all a very large difficult problem, the sampling cotton swab easy to break that a lot of companies produce finally must be cut by scissors, the problem finally caused is the same with the first cotton swab, may bring the pollution of extra microorganism.
The thief rod of above two kinds of cotton swabs after cutting off all can not be reused, and causes the wasting of resources.
Utility model content
The utility model provides the detachable sampling cotton swab of a kind of cleaning validation, and refer to and performing a kind of cotton swab used in cleaning validation sampling process, solve the pollution problem that may there is extra microorganism, its technical scheme is as described below:
The detachable sampling cotton swab of a kind of cleaning validation, comprise sampling head, thief rod, described thief rod is connected by helical structure with sampling head.
The cross section of described sampling head is oval.
Described sampling head is provided with screw rod, and described thief rod is provided with corresponding helical cavity.
Described cotton swab is at oblate test tube or have oblate test tube mouth and carry out being separated of sampling head and thief rod.
The described cleaning validation detachable sampling cotton swab chemical cotton swab that can be used in pharmaceutical industry cleaning validation process samples and the sampling of microorganism cotton swab, its sampling method does not change, just after sampling completes, sampling cotton swab changes to the detachment process of glass test tube, cut off without scissors, only need to grasp thief rod to be rotated counterclockwise, being separated of sampling head and thief rod can be realized.Thief rod after separation is recyclable and reuse, and avoids the wasting of resources.

Embodiment
Cleaning validation is used to the process proving that workshop appliance clean method is effective, can reach cleaning performance, and the process of producing product is pollution course equally concerning equipment, and produce after terminating, this equipment cleans according to set cleaning method.
In order to confirm whether this equipment cleans up after cleaning terminates, need sample equipment surface and detect.Need to get two kinds of samples with cotton swab, one is chemical residual, namely checks whether the effective constituent of this medicine cleans up; A kind of remain for microorganism, namely whether checkout facility surface microorganism after cleaning remains in tolerance interval.
Sampling method carries out wiping, with 5 × 5cm by cotton swab equipment surface after cleaning
2teflon frame is as sampling scope, in wiping process, dip in a small amount of clear first horizontal wiping of purified water with cotton swab, then overturn cotton swab longitudinal wiping again, respectively as shown in Figure 1 a, 1 b, notice that cotton swab, can not wiping back and forth necessarily along a direction wiping when wiping.Require in wiping process all will clip within the scope of tygon tetrafluoro frame.
This detachable sampling cotton swab as shown in Figure 2, is made up of two parts, i.e. sampling head 1 and thief rod 3.Sampling head 1 and thief rod 3 adopt helical structure 2 to be fixed together, and described sampling head 1 is provided with screw rod 21, and described thief rod 3 is provided with corresponding helical cavity 22.After sampling terminates, can be separated by hand.Needs and specific glass test tube 4 support the use, and former glass test tube mouth is positive circular, can not block cotton swab, improved glass test tube mouth is in oblate, in cotton swab detachment process, sampling head 1 can be blocked, to assist to carry out being separated of sampling head 1 and cotton swab bar 3.
After cotton swab completes, sampling head 1 is put into oblate test tube 4, is rotated counterclockwise cotton swab bar 3 with hand, sampling head 1 is separated with cotton swab bar 3, after being separated, carry out mark, control laboratory can be delivered to and test.
Claims (4)
1. the detachable sampling cotton swab of cleaning validation, it is characterized in that: comprise sampling head, thief rod, described thief rod is connected by helical structure with sampling head.
2. the detachable sampling cotton swab of cleaning validation according to claim 1, is characterized in that: the cross section of described sampling head is for oval.
3. the detachable sampling cotton swab of cleaning validation according to claim 1, is characterized in that: described sampling head is provided with screw rod, and described thief rod is provided with corresponding helical cavity.
4. the detachable sampling cotton swab of cleaning validation according to claim 1, is characterized in that: described cotton swab is at oblate test tube or have oblate test tube mouth and carry out being separated of sampling head and thief rod.
